Avoid Modifying `require.paths`

[fernandoacorreia]

example/Jakefile.js and lib/templates/Jakefile.js.ejs modify require.paths. This was not advised and has been deprecated as of v0.5.4.

See http://nodejs.org/docs/v0.4.8/api/all.html#loading_from_the_require.paths_Folders

require.paths may disappear in a future release.

While it seemed like a good idea at the time, and enabled a lot of useful experimentation, in practice a mutable require.paths list is often a troublesome source of confusion and headaches.
